Falk Wrapflex Elastomeric ouplings A Simple Way to Increase Productivity 9 sizes Torque range: 15,027 Nm (133,000 lb-in) Bore capacity: 190 mm (7.25 ) Replace in place Non-lubricated/low maintenance Quick, easy installation and replacement set new standards for reduced downtime. Because motors or drives don t need to be moved, our replace in place elements even eliminate the need for time-consuming realignment. Available in close-coupled and spacer designs, Wrapflex couplings accommodate up to 190 mm (7.25 ) shafts and torque loads up to 15,027 Nm (133,000 lb-in). For simplicity and cost-effectiveness over the life of your coupling, it doesn t get any easier than Wrapflex couplings from Rexnord. Low Initial ost Advanced manufacturing methods and innovative material allow us to offer higher capacity ratings at a more competitive price than ever before possible. Easy to Install The compound root radius in the element teeth (patent #6,342,011) increases flexibility for easier and quicker assembly. The coupling can be blind assembled from either direction. Protects Equipment ompound root radius on inner corners of flex element (patent #6,342,011) acts as a stress relief for longer element life. Special hub feature reduces reaction loads transferred to connected equipment (patent #6,648,763). Tough, Long-Lasting Polyurethane element has excellent wear and chemical resistance, and an operating temperature of -40 (-40 F) to 95 (200 F). Weather-resistant, high-grade nylon cover is standard. Optional carbon steel covers with black epoxy coating are suitable for highlycorrosive, severe-duty applications. (Standard for sizes 60-80.) Optional stainless steel hubs are available for Type R10 when required in the food industry or corrosive environments. ontact Rexnord for Stainless Steel availability. Safety First Two stainless steel button head cap screws, positioned 180 apart, prevent relative motion between cover and element and provide a positive means of retaining the cover to the element. Flexible element is retained after failure, helping minimize the potential for damage or personal injury. Quick and Easy Retrofits ompact design eliminates the need for coupling guard redesign on existing applications. Stock finished bores in popular sizes. Taper bores for QD and Taper-Lock bushings are available off-the-shelf from our worldwide distribution network. Replace in Place Design allows quick and easy element replacement. There s no need to remove hubs or realign motors or drives, so downtime is reduced. No Maintenance Needed Non-lubricated design of the tough, flexible polyurethane element lowers periodic maintenance costs. (491-110M) 3

Falk Wrapflex oupling Selection Wrapflex Quick Selection Method 1. Determine Service Factor Refer to Table 1or 4 for motor or turbine driven applications. See Table 5 for engine drives. 2. Determine Equivalent Power: Refer to Table 2 Under the actual kw required and opposite the service factor, read the equivalent kw. 3. Determine oupling : A. Refer to Table 3 Trace horizontally from the required speed to a kw value equal to or larger than the equivalent kw determined in Step 2. Read the coupling size at the top of the column. B. heck shaft diameters against coupling maximum bores shown in Table 3 and on page 7 thru 11 for the correct coupling size selected.. In Table 3, check the required speed against the allowable speed shown below the correct coupling size selected. 4. Determine oupling Dimensional Requirements: A. Determine application/design shaft spacing and check application dimension requirements against selected coupling type dimensions shown on page 7 thru 11. onfirm sufficient clearances for coupling. 5. onfirm that application ambient operating temperatures are between -40 (-40 F) to 95 (200 F). For applications requiring Service Factor above 1.5 and temperatures above 79 (175 F), consult Rexnord Engineering for selection assistance or optional high temperature elements. Service Factors are a guide, based on experience, of the ratio between coupling catalog rating and system characteristics. The system characteristics are best measured with a torque meter.

BE = Standard Distance Between Shaft Ends with hubs mounted flush to the shaft ends. GAP = Minimum allowable Distance Between Shaft Ends. Any shaft end spacing between the GAP and BE dimensions is acceptable. However, if utilizing a shaft end spacing less than the BE dimension, the key should not extend beyond the hub face in order to prevent potential interference with the flex element. fasteners are stainless steel, socket button head cap screws, per ISO 7380-A2.
